This update for abseil-cpp, grpc, opencensus-proto, protobuf, python-abseil, python-grpcio, re2 fixes the following issues: abseil-cpp was updated to: Update to 20230802.1: * Add StdcppWaiter to the end of the list of waiter implementations Update to 20230802.0 What"s New: * Added the nullability library for designating the expected nullability of pointers. Currently these serve as annotations only, but it is expected that compilers will one day be able to use these annotations for diagnostic purposes. * Added the prefetch library as a portable layer for moving data into caches before it is read. * Abseil"s hash tables now detect many more programming errors in debug and sanitizer builds. * Abseil"s synchronization objects now differentiate absolute waits from relative waits when the underlying platform supports differentiating these cases. This only makes a difference when system clocks are adjusted. * Abseil"s flag parsing library includes additional methods that make it easier to use when another library also expects to be able to parse flags. * absl::string_view is now available as a smaller target, @com_google_absl//absl/strings:string_view, so that users may use this library without depending on the much larger @com_google_absl//absl/strings target. Update to 20230125.3 Details can be found on: https://github.com/abseil/abseil-cpp/releases/tag/20230125.3 Update to 20230125.2 What"s New: The Abseil logging library has been released. This library provides facilities for writing short text messages about the status of a program to stderr, disk files, or other sinks . See the logging library documentation for more information. An extension point, AbslStringify, allows user-defined types to seamlessly work with Abseil#x27;s string formatting functions like absl::StrCat and absl::StrFormat. A library for computing CRC32C checksums has been added. Floating-point parsing now uses the Eisel-Lemire algorithm, which provides a significant speed improvement. The flags library now provides suggestions for the closest flag in the case of misspelled flags. Using CMake to install Abseil now makes the installed artifacts reflect the compiled ABI. Breaking Changes: Abseil now requires at least C++14 and follows Google#x27;s Foundational C++ Support Policy. See this table for a list of currently supported versions compilers, platforms, and build tools. The legacy spellings of the thread annotation macros/functions have been removed by default in favor of the ABSL_ prefixed versions due to clashes with other libraries. The compatibility macro ABSL_LEGACY_THREAD_ANNOTATIONS can be defined on the compile command-line to temporarily restore these spellings, but this compatibility macro will be removed in the future. Known Issues The Abseil logging library in this release is not a feature-complete replacement for glog yet. VLOG and DFATAL are examples of features that have not yet been released. Update to version 20220623.0 What"s New: * Added absl::AnyInvocable, a move-only function type. * Added absl::CordBuffer, a type for buffering data for eventual inclusion an absl::Cord, which is useful for writing zero-copy code. * Added support for command-line flags of type absl::optional and less than T greater than. Breaking Changes: * CMake builds now use the flag ABSL_BUILD_TESTING to control whether or not unit tests are built. * The ABSL_DEPRECATED macro now works with the GCC compiler. GCC users that are experiencing new warnings can use -Wno-deprecated-declatations silence the warnings or use -Wno-error=deprecated-declarations to see warnings but not fail the build. * ABSL_CONST_INIT uses the C++20 keyword constinit when available. Some compilers are more strict about where this keyword must appear compared to the pre-C++20 implementation. * Bazel builds now depend on the bazelbuild/bazel-skylib repository. See Abseil"s WORKSPACE file for an example of how to add this dependency. Other: * This will be the last release to support C++11. Future releases will require at least C++14. grpc was updated to 1.60: Update to release 1.60 * Implemented dualstack IPv4 and IPv6 backend support, as per draft gRFC A61. xDS support currently guarded by GRPC_EXPERIMENTAL_XDS_DUALSTACK_ENDPOINTS env var. * Support for setting proxy for addresses. * Add v1 reflection. update to 1.59.3: * Security - Revocation: Crl backport to 1.59.
